VVAR BRAKE AND STARTER.

SPECIFICATION forming part of Letters Patent No.359,386, dated March l5,1887.

Application iiled December 22, 1886. Serial No. 222,319. (No model.) v

drawings, in which- Figure 1 represents a side elevation of myinvention, and Fig. 2 a bottom view thereof. In the drawings, the letterA indicates the platform of an ordinary streetecar, mounted upon thelwheels B, and having also the usual brake-handles provided with the pawland ratchet at the platform to hold the brake to its position againstthe wheels and the usual extension below the platform on which the chainis wound.

Iivoted eccentrically to the bottom'of the car are the irregular camsO,one at each end. Resting upon the car-wheel axles is the frameD,having secured thereto one side of a springhinge, the other side beingsecured to a crossbar, E, having at each end the slotted brakeshoes F,in the slotl of which are the pivoted dogs G, one endof which isenlarged.

Theirregular cams mentioned above are connected to the cross-bars E bymeans of the rods H and short chains I, andthe brake-operating means,substantially handles are connected to the irregular cams by the chainsJ. The purposes of these de scribed parts will be hereinafter described.

The operation of my invention is as follows: To stop the car,theoperatorturns the handles,

winding the chain attached thereto around its lower end, turning theirregular cam upon its Y pivot, drawing the brake-shoes toward thecarwheels through the medium of the short chains and rods, and when thebrake-shoes are travelingin the forward direction the pivoted dogs,being weighted by their enlarged ends,fall by gravity,striking theground, but, giving freely, allow the shoes to press against the wheels;but when the brake-handles are released the springhinge draws themechanism toward its normal position, when in the backward motion of thebrake-'shoes the pivoted dogsirnpinge thetraek,

forcing the car forward,thereby taking off the strain forced upon thehorses attached to the car when starting. I

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is f A car brakeand sta-rter consisting ofaspringhinge, a cross-bar having slotted brake-shoes thereon, withpivoted dogs therein, and the irregular cams pivoted eccentrically tothe bottom of the car and attached to the brakehaudles andshoe-supporting bars by suitable as described.
